- Specification of Letters Patent. Patented NOV. 12, 1912.

Application filed December 21, 1909. Serial No. 584,254.

To all whom it may cancer-n:

Be it known that 1, Joint W. KING, a citizen of the United States of America,

and a resident of the borough of Bronx, in

the city of New York, county of New York, and State of'New York, have invented certain new and useful Improvements in Dumping-Receptacles, of which the followlar application is to dumping-cars of the class in which the gate is unfolded downward to discharge the burden when the body is tilted, and in which the gate is restored to its normal position when the body is righted after discharging its contents.

It ha's for its object the provision of means for effecting automatically the unfolding of the gate, to form an apron for the further discharge of the burden, andfor eifecting automatically and positively the closing of the gate and looking it securelyin position by the operation of restoring the receptacle to its normal position.

A further object is to make the means provided of a character embodying advantages in point of operation, simplicity and inexpcnsivcness.

A further object is to make a suitably formed cam a part of the mechanism for controlling the unfolding and folding of the gate whereby the constructor is free to'give it such shape as will cause the gate to move relatively to the movementof the body according to any desired law.

These objects I accomplish by hinging or pivoting the gate at or near the plane of the floor, automatically unfolding the same as the car is inclined to dump until it attains a position in preferably, though not neces-.

sarily, the same plane but adjacent to the floor of the car, and forms thereby an -extended apron or continuation of the said floor over which the load must pass. I thus deliver the load farther from the center of the track, eliminate the possibility of jamming or skimming and consequent hindrance to the discharging burden in the actof dumping as is the case where a gate is raised ..'and the load dumped between the car and the gate, and provide for the discharge of larger fragments of rock than in the last named case without liability of accident or delay. Upon restoring the body to its normal position, the gate is automatically and POSILIVBIV returned and locked in its position and the construction is so formed that the body is atthe same time locked from a horizontal displacement.

In the art of removing material and of grading, dumping vehicles of various types have been employed, for example, some dumping from one end only, or from either end or from both ends; others from one side only, or from either side or' from both sides:

and various means have been employed for tilting them, for example, air, steam, or simply by hand. But the particular type of vehicle or manner oftilting is not a part of this invention; which is designed, to have general applicability. to all dumping de- For purposes of illustration only, the gate and its attending mechanism have been shown attached to a railway car dumping from either; side and tilted by hand, as being the most common form of its application, but it is not my desire to bein any way limited to this particular type o-rmanner of tilting. a a

In theaccompanying two sheets of draW-' ings, which form a part'of this application Figure 1 is a sideelevationshowing-are ceptacle in its normal position constructed i in accordance' with my 1nv,ention,-1 and forming the body of a du1npcar. Fig. 2 is an end view of the same. Fig. 3 is an end view of the same showing in full lines the receptacle inclined for dumping, and in dotted lines the position of the receptacle; partly inclined. v v -An underframc a of the cart supports a moving body I) which contains the burden and is inclined to dump and discharge the contents. This body is surmounted upon the underframe a and supported thereon by any of the various forms of binge devices 0 and secured in place by any oi th e variousmeans that are now employed, one ofwhicliic onsisting of chains m being shown. f l

The gates which are hinged at their law edge to the floor are attached at-their ends to downwardly extending levers e respectively, which are also hinged coincidentally at the lower edge of thd gates inthe plane of the floor by the pivot points f 1" respectively, about which the gates 51' d respec- ,blocks g gif'body reaches its normal upright position,

tively turn, the upper end of the levers being held in a vertical position by the v thrust blocks h h respeetively When the body of the car is tired for 'dum ing on the side illustrated In Fig. 1, the evers e e' are allowed to slide around the thrust blocks h h respectively, the relative position of said levers depending on the inclination of the car body 6 and the move- 10 ment of the pivot point around said thrust blocks. A relative movement of the gate in a downwardly and outwardly direction is thus secured, until the body. reaches its ,m, aximum inclination, at which point the 1; lower ends of the levers e have assed around the outer ed e of the thrust locks h and rest-on its un er sidery and the lovers 6 lie parallel to the plane of the floor, while the gate d secured to the opposite endsof' the levers 6 lie parallel to and in the same plane as the car-floor rovidin a'continuat-iou or. anextension t ereof. n the opposite and elevatedsideof the body b the gate (1' secured similarly to levers e pivoted in like manner at f disengages from thrust block's k as the body is inclined to dump, and remains in its normal osition relative tothe floor of the car an is held in this position b the action of gravity.- When 30 restorin t e body to its normal upright position t e levers e descendfrom the elevated position until they come 'in contact with up er and outer surfaces of the thrust ii upon which they slide until the coincident with locking of the gate (1. 1 The closing of the gate d' is accomplished in a Inanner'that is positive throughout its" operation and in a direct relation with. the :40 movement of the body, in which the inwardly extending portions of the arms a resting against the underside of the stationary thrust blocks or cams it slide outwardly and upwardly as the body .is raised, acting upon the fulcrum pivots f and forcing the gate to acquire a corresponding upwardly and inwardly movement until the body reaches its normal upright position where the thrust blocks hand It maintainingthe levers e and e in'their respective extended position close their respective gates d and d and lock the car body against a horizontal or lateral displacement in either direction.

'60 downwardly projecting portions... of gate While I have only described the operation of my construction when the body is tilted for dumping on the side illustrated in Fig.

1, it is obvious'that corresponding parts ,would operate in like manner when the body 60 is tilted for dumping on the opposite side,

I or on the end if the body were mounted for the last named purpose.

,substantially as described. 3.
